No Houston trip for First Lady

Michelle Obama was scheduled to be in Houston Tuesday night for a glitzy Democratic fundraiser at the River Oaks mansion of Laura and John Arnold, but a Democratic official, speaking on background, said the event had been postponed because of a scheduling conflict. The official said the event would be rescheduled but the date has not been determined.

Laura Arnold and her husband John, a Houston billionaire and former Enron trader, were planning to greet guests who who paid $10,000 to attend or couples who paid $15,000. A 5:30 reception cost $250.
